“Uncle Sam Says Garden” was a poster that was directed to wider audiences than some of the other gardening posters, which were directed to children. Produced in 1917, it shows Uncle Sam in the foreground, holding a hoe in one hand, and papers that read “City Gardens” and “Farm Gardens” in the other. These words are clearly meant to synthesize the interests of rural and urban Americans: gardening was a shared activity, a common national goal. A man and woman work in the garden shown, which is in the shape of the American flag. Some of the plants featured in the garden might appear to be stars upon the flag. The woman in the poster wears a long, red skirt and a white shirt; in her arm is something she has harvested from the garden.

A subtitle suggests that Americans might wish to garden in order to “cut food costs.” Those seeing the poster are urged to write to the USDA for a free bulletin on gardening, suggesting, “It's food for thought.” The poster is framed by brown band, and the bottom right corner features a cluster of richly hued vegetables. Upon careful inspection, the background, featuring trees, actually bears a striking resemblance to leafy green vegetables and also to broccoli stems. The use of Uncle Sam in gardening posters was not as common as Columbia, and in this depiction, he is dressed in clothing covered with stars and stripes, and has a piercing game.

This poster offers a message that is still food for thought, don't you think?
